Another Colnago enthusiast and myself have embarked on creating a website that will allow you narrow down the vintage of your Colnago. This is intended to run with a database of photos, identifying details and known frames. This will span 60's to modern day with the majority of (my) interest being OT years. I have received several emails from my inquiry about 6 weeks ago on an early 80's Super. As the framework is decided upon, I'll prod those of you that have an interest specifically in Colnago's for additional photos and information.
I hope that this work will be of value. I'm rather surprised it doesn't exist with the large amounts of Colnago's produced.
